If you lived through the 90s it's impossible that you didn't hear their hit song "Jump". It stayed at number one on the Billboard charts for eight weeks, and was played in clubs incessantly for years after. They were also known for their penchant for wearing their clothes backwards, and more than a few copied the look back in the day.

According to TMZ, Kelly was found in his Atlanta home this evening, and pronounced dead at 5:33 p.m. As of yet, no cause of death has been declared.

Many people are reeling from the news tonight that seems so sudden. Twitter is a flurry of messages of sorrow and remembrances for the rapper from those in the industry and those who just loved his music:

I'm so sad to hear the news of Chris Kelly. What a great loss. RIP Mac Daddy. -- @LilKim
